1. First turn the car on but donít start it. If you push the any of the buttons does it change the air flow or just blow out of all vents? If not then I think your system is in malfunctioning mode it goes into an override function.
2. Does the fan seem to go on and off intermittently? Itís actually not, it is timed in seconds.
3. Just count the seconds or use a stop watch, after one clicking noise from the relay the fan will go on for XX seconds pause for four then on another same XX seconds and so on. The number of XX seconds should be the same and not intermittently, this number should also tell you what is wrong with your system.
